Device powers on and charges etc. Heres the deal, swapped out the USB C ports because it was not charging, charges now, but now the USB C ports kill my external devices (USB EXTERNAL THUMBDRIVES) . so far it killed three thumbdrives. Again macbook operates normally and charges, but I cannot connect any external devices to the ports until I figure out what is causing this issue. Remember I swapped out multiple USB C ports and they all are causing the same issue, even with . new ones. So if there needs to be a logic board repair can someone point me to the right direction?

Hello there
I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.
I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.

Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.
⚠️ New Problem: One USB-C Port Only Works in One Orientation... -
Hi, I'm having a problem with my MacBook Pro A1707.
There are graphics glitches all over the screen.
I took a screenshot, so it's not a screen issue, but either the graphics card or VRAM chips.
Has anyone had this issue before? I don't want to replace unnecessary components.
The system is otherwise quite stable, it's just a visual problem.
Thanks.... -
Hello, got a weird MacBook Air here
board looks fresh and no water damage, backlight works and turns on and stays on when installing OS etc. However, when the os is installed and when the system files are loaded before the login page the backlight goes out. I have wiped it, NVRAM reset, etc and even took some other instances and this blows my mind, never seen this before. Backlight just turns off once the OS is loaded. Anyone come across this and if so what would be the cause? I am certain its a board issue since I tested the LCD on another board and it stays on. Again the backlight works... -
Hi guys I have a Macbook a1707 with motherboard 820-00281, without liquid damage that behaves strangely, with the battery connected the Macbook does not turn on and the USBC meter stops at 5v in loop, when I disconnect the battery the Macbook turns on and works fine, I have already tried to replace the battery twice without success, as soon as I connect the black cable of the battery the Macbook does not turn on, it stops at 5v and in loop.
